'UNITED STATES PATENT OFFICE.,

HORATIO GALE, OF ALBION, MICHIGAN.

IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 159,174, dated January26, 1375 5 application filed December 11, 1874.

To all whom it may concern:

Be it known that I, HORATIO GALE, of Albion, in the county of Calhounand State of Michigan, have invented an Improvement in Plows, of whichthe following is a specification:

The first part of my invention relates to the peculiar method ofsecuring the colter of a plow to the standard, in such a way that it canreadily be adjusted in both the horizontal and the vertical planes. Thesecond part of my invention relates to the devices for securing thehandles to the standard of a centerdraft plow, which handles areadjustable to pitch, as more fully hereinafter set forth.

Figure l is a perspective view. Fig. 2 is a vertical' cross-section ofthe standard and colter-block at a; @c in Fig. 1. Fig. 3 is a horizontalsection through the front ends of the handles in the plane y y. Fig. etis a perspective view of the washer. t

In the drawing, A represents the standard, and B the beam, of acenter-draft plow. The land-side face of said standard is cast withhorizontal serrations to receive and engage corresponding serrations onthe inner face of a block, C, attached to the standard by a bolt, c,passing through both. The outer face of the block has a longitudinalrecess molded in it to receive the horizontally-bent shank of the colterD, which is slot-ted to receive the bolt a, which thus secures thecolter and block to the standard7 the bolt-hole of which is a verticalslot t-o permit the block to be adjusted up or down, as circumstancesmay require. The bolt-hole in the colter-shank may be a longitudinalslot, to adjust the colter longitudinally, but in practice suchadjustment will not often be found necessary. The shank or upper end ofthe standard extends through the beam, terminating in a stud-bolt, uponwhich is sleeved a triangular Washer, E, up through which the shank ofthe standard passes, and is secured by a nut on the upper end of saidshank, in front of which a horizontal hole is cored in the said washer,against the sides of which the front ends of the handles are brought,and are secured thereto by a bolt, b, passing through all. lhe handlesare adjustable as to pitch by bolts passing through Vertical slots in aforked jack rising from the shelf-piece at the top ofthe heel standard.

The advantages of this construction are that the handles for varioussizes of plows are all of one size, tting and adjustable toall sizes,can be compactly stowed for shipment, and are cheap in construction, asit enables the manufacturer to make all his plow-handles of uniform sizeand shape, with special machinery.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. rlhe horizontally-recessed and serrated collier-block C, incombination with a serrated plow-standard, substantially as described.

2. The triangular washer E, combined with the standard-shank and handlesof a plow, substantially as and for the purpose set forth.
